Describe the two different motivations, Kamya and Nishkam, for which Guru biography texts are used.

As explained in Chapter 0, both knowledge texts and Guru biography texts are used in two distinct ways: with desire (Kamya) and with a selfless mind (Nishkam). The Kamya approach involves using the texts for worldly purposes, such as attaining prosperity or seeking the removal of worries, calamities, distress, and diseases. The Nishkam approach, on the other hand, is selfless and is undertaken for the ultimate goal of liberation from the world and freedom from the cycle of birth and death. The text emphasizes that Nishkam Guru service is always considered superior.
